raspberry pi TTS without using browser

[Roger]

Anyone experience with tts on raspberry pi without the use of a webbrowser?

I want to connect a speaker to the audio output of the pi

Have a working solution with use of my browser, but what i am looking for is without the browser

Thanks

[Colin Law]

This link has a number of suggestions for doing text to speech (I
presume that is what you mean by tts) without the use of a browser.
Not sure what the question has to do with node-red though.

Thanks Colin!

It has to do with node-red because i use node red for the whole system and want node-red to speak for me.

Hi Roger,

I've used espeak (mentioned on the link Colin provided) as a simple way to do TTS. The missing link is to use the node-red exec node to invoke the appropriate command.

Thanks guys!!

Testing now with the "play audio node"

But when i use 2 nodes with different language i get the same language from both nodes.

Were can i find who is the developer of this node to ask about this?

Thanks

Rogier

Which module is that node from? node-red-contrib-???

If you search for that on GitHub you should find its repository and info.

Finally i use the audio out function node of the dashboard.

This works great!

What i am trying to find out now is to detect when the node finished speaking

Thinking about counting the letters and the this in seconds or so...

Or some one a better solution to detect this?

[Niels vd spek]

I use this subflow to allow the use of espeak. It has a queue that stores new text while other text is speaking out,
